2021-02-27 11:42:54 UTC (2021-02-27) · approx. 11:42 PM UTC+12 local
On February 27, 2021 at 11:42 UTC, a magnitude 4.8 intermediate depth earthquake struck 19 km NNW of Turangi, New Zealand, at a depth of 124.9 km and coordinates -38.8205°, 175.7369°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in New Zealand, a region characterized by the Hikurangi subduction zone in the North Island and the Alpine Fault in the South Island. The nearest mapped fault system is the Alpine Fault. View all earthquakes in New Zealand.
